Abstract

Porous aluminium oxide layers are formed by anodising the article in a bath contg. 1.5-50 wt.% (10-12) wt.% H3PO4 at 10-30 (21-24) degrees C, and using an anodising voltage of 1.50-50 (10-15) volts. Pref. the anodising process is carried out for 10-30 (20-25) mins., and the article is rinsed within 0.3-2.3 mins. after anodising is completed. The process is useful for pretreating aluminium articles which are to be bonded with polymeric adhesives such as epoxy adhesives, e.g. in aircraft manufacture. The porous aluminium oxide layer formed is compatible with polymeric adhesives and gives high bond strengths. The resulting adhesive bonds have high resistance to hydrolysis and failure of the bond is generally by cohesive failure in the glue line rather than adhesive failure in the oxide layer or at the glue/oxide interface.
